There is ___ little time before the exam!

• A. So
• B. Very
• C. Much
• D. Few

Answer: (A)

The idea being tested is how to intensify a small amount for an uncountable noun like time to express urgency. When you want to emphasize just how small the amount is, the pattern so + little is a common, strongly emphatic choice. In this context, there is so little time before the exam! sounds more urgent and expressive than there is very little time, which is more neutral. Time is uncountable, so few wouldn’t be correct here. Much little time isn’t natural in this construction. That’s why so fits best: it heightens the scarcity of time and suits the exclamatory tone.
